ANTI-eRATTLER FOR THlLL-COUPLINGS.

SPECIFICATION forming part of Letters Patent No. 223,731, dated January20, 1880.

I Application filod May 19, 1879.

To all whom it may concern Be it known that I, JOSEPH S. HEALEY, of EastWeymouth, in the county of Norfolk and State of Massachusetts, haveinvented an Improvement in Anti-Battling Shaft-Holding Springs, of whichthe following is aspecification.

Thisinvention relates 'to a coiled spring to prevent shaft-shackles uponvehicles from rat- :0 tling as the bolt becomes worn, or if the boltfails from any cause to properly fit the shaftiron.

Figure 1 represents this invention applied to an ordinary shaft-shackle;Fig. 2, the spring in perspective.

' It is well known that shaft-couplings when first made, if looselyfitted, or after being worn a short time, rattle. To overcome thisdifficulty many vehicles are supplied with shaft- -26 shackles speciallyconstructed, and thereby made expensive, to prevent rattling. One mostcommon plan for this purpose is the insertion of a yielding block ofindia-rubber.

- Flat steel springs have also been used. The spring herein described,and constitutin g an improved article of manufacture, is composed of asingle piece of wire bent, as herein shown and described, to form aspring, and so as to embrace the rear portion of the shaft-iron, 30 andso as to hook over the forwardly-projecting side ears of the clip. Thewire is coiled at d g to form two short springs, one in line with theother. The central portions, of, extended therefrom, are curved to fitthe rounded portion,j, of the shaft-iron, and the end portions, '5 h,made to diverge as they leave the coiled portionsdg, are provided withhooks a I), bent so as to extend parallel with the axes ordinaryshaft-shackles.

of the coils and the boltholding the thills in i the clip. 3 40 The eye3' of the shaft-iron k is entered by the bolt Z, carried by the clippart 0, attached to the axle n, as usual. The spring is inserted betweenthe clip and the convex portion of the eye j. 5

These springs are intended to be applied to I find it impossible toretain the springs in place for any length of time unless the hooks a bengage the side ears,

m n, of the clip part. The small horizontal 5o ledge formed on the clippart immediately at the front of the axle is, I have found in practice,insufficient.

.'I do not broadly claim a wire spring irxe spective of its specialconstruction and adaptation. v

As an improved article of manufacture, an an ti-rattlin g shaft-holdin gspring composed of a single piece of wire bent as shown, the por- 6otions 0 f being curved to fit the rounded eye part of the shaft-iron,and the hooked ends a I) of the diverging portions. h ibein g bentoutward in'the direction of the axes of the coils d g, so as to engagethe forwardly-projecting J OSEPH- S.
